the particles have large gaps in them
yes there are
The rubber band particles are compressed together from the top and bottom and outwards on both sides, this creates a lot of pressure and the particles spring back once you let go.
plastic balloons lose air because particles are moving in the balloon and leave it
No a pencil is made of wood, graphite, and rubber, which are all insulators, however the aluminum part surrounding the eraser could conduct electricity
Rubber is a compound with large molecules loosely bound by hydrogen bonding and is holey as it is stretched. Coating a balloon with aluminum which has atoms regularly spaced, forms a cohesive layer with less space between particles and less holes.

Steel, aluminum, rubber and plastics
Because copper and aluminum are good conductors and therefore are more efficient. They are wrapped in rubber so that it can insulate the charge and energy is not wasted that way. Also its wrapped in rubber for protection.
